The Kaw Valley Precision AR-15 Adjustable Gas Block, .750” (Kaw Valley Precision part no. KVPGB750A) is sized for barrels with a .750-inch gas block journal diameter and includes an adjustable set screw that lets shooters dial back gas flow on suppressed or otherwise over-gassed AR15 builds. Reducing excess gas can soften felt recoil, reduce bolt carrier wear, and cut down on the gas blowback common with suppressors. The low-profile design still fits underneath most free-float handguards without needing modification. Kaw Valley Precision machines the block to hold a secure fit with set screws locking both position and the adjustment setting.
